CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 288,270, dated November 1?, 1883. Application filed August 2l, 1883. (No model) Y and exact description.

This invention relates to the class of carcouplings inwhich the-ordinary coupling link and pin are employed. y

The invention consists in improved means for guiding the link connected with the draw- `bar of one car into the mouth of the draw-bar of the approaching car in the operation of coupling the saine, whereby said coupling can be effected with theutmost convenience and safety to the operator. ,o

The invention is fully illustrated in the annexed drawings, whereiu'ligure l is a perspoot-ive view of a set of draw-headsprovided with my improvements, and showing their position prepzfiratory to .couplingthem Fig. 2

is a vertical longitudinal section of the same; and Fig. Sis a detail view of the cani or adjust-able support, by means of whichthe link is guided into the mouth of the approaching draw-head.

Similar letters of reference indicate corre- 'sponding parts.

A represents the draw-head, of the ordinary form. B denotes the coupling-link, and C the usual coupling-pin, which. passes vertically through the draw-head and through the link B.. ln front of the coupling-pin C, inthe mouth or cavity of the draw-head, is a cam or linkguide, c, in the form of a plate, lying under the link, and projecting upward onV opposite sides thereof. Said cam is pivoted in ,its position by means of manipulating-rods b b, which pass through the sides of the draw-head and are firmly secured to the sides of the cam a. Said manipulating-rods are extended to opposide sides of the car, so as to be convenient of access from either side without the entrance of the operator between the cars. The outer ends of the manipulatingrods are terminated in cranked arms b', which are turned at such an angle and are weighted in such a manner as to automatically retain the cam a, lying close to the bottom of the interior of the drawhead, and thus leave the entrance into the draw-head unobstructed. Byturning the inanipulating-rods b b the `cam c can be raised to bring the sup erincunibent link B in range with the mouth of the approaching draw-head preparatory to couplingit therewith, as illustrated in Figs, l and 2 ofthe drawings.

The engagement of the coupling-pin C with the link entering the approaching draw-head, Vas aforesaid, is eifected automatically, as in sonic other car-coupling devices, and consists in the following instrumentalities: In the cavity of the draw-head is arranged a movable support for sustaining the couplingpin above the aforesaid cavity, said support consisting of aplate, c, which slides longitudinally in a dovetailed groove, f, in the top of .the interior of the draw-head, and is adapted to move across the passage of the couplingpin, and

thus 'support said pin abovethe cavity of the draw-head, as illustrated in the annexed drawings. slide c into the position forl sustaining the coupling-pin, said parts are connected by'a chain, c, and the draw-head is provided with a longitudinal slot, d, for the travel of saidv chain, the chain being of the requisite length to compelfthe pin C to draw the slide forward and across the passage of the pin simultane ously with the entrance of the latter into the usual eye, g, in the top ofthe drawhead. From the under side of the forward end of the slide c projects a pendent pin or lug, lz', which the end of the couplinglink of the approaching draw-head encounters, and thereby drives the slide back and causes the pin to drop into the link. t v

I donot claim, broadly, alink-lifter carried byv the draw-bar and adapted to raise and guide the link in making the coupling, as I am aware the same has been used in connection `with a draw-bar having the buffer formed hy a base extension from the open end of the draw-bar, butin this case the link-lifter extended around the exterior tof the draw-bar, and was supported outside of the draw-bar by the projection of the buffer; This arrangement exposes the link-lifter to snowand ice, which are liable to gather on the projecting In order to automatically bring the,

IOO

buffer, and thus frequently render the same inoperative, whereas by my improvement the link-lifter is housed in the mouth of the draw.- bar, and thus protected. Furthermore, I dis- 5 pense with the eXtra projection at the base of the draw-bar, which projection, when made to serve as a buffer, exerts undue downward strain on theA draw-bar, and is liable to produce breakage ofthe same or of its fastenings; 1o hence f Vhat I claim as new, and desire to secure by Letters Patent, is-

The combination, with a draw-bar, of the within-described link-lifter, housed in the mouth of the draw-bar, substantially as set r 5 forth and shown. l

In testimony whereof Ihavehereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, 2o this 3d day of August, 1883. I
